BORING AND TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 263,702, dated September 5, 1882. Application filed April 1, 1882. (No model.)

' To all whom it may concern and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, makinga part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of this invention. Fig.2 is a view of the opposite side. Fig. 3 represents details. Fig. 4. is a plan view. Fig. 5 is a detail section.

This invention has relation to boring and tenoning machines; and it consists in the con" struction-and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims appended.

In the accompanying drawings, the letter A designates the main bench, and B its legs or supports. Lateral slots 0r grooves a, are made longitudinally in the bench to receive and guide the supports 11 of the slide-table O, to which the Work is secured.

D represents an adjustable post or bearing, located near one end of the main bench, an d connected .thereto by means of sliding projections 0, which engage grooves or ways at in a foot-bearing or upright, E, which is firmly secured to the bench. The post is vertically slotted at e, and is provided with transverse bearings g for the driving,shaft h and the shaft k, to which the hollow anger or boring-bit is attached.

Pivoted to the upright E is a T-lever, l, to the lateral arms of which are connected treadlcs F.

To the upright arm of the lever is pivoted a connecting-rod,.m, which is flat in form, and is perforated at quarter-inch distances or less along its length, as indicated at a. This rod extends under the work-table U, and is connected thereto by means of a pin, 19, which passes through a bearing in said table into one of the perforations a of the rod, this perforation being determined by the depth of boring action required. In this manner the slide-table is easily adjusted, so that the boring or tenon ing operation will be continued to the exact distance required. The connecting-rod m is graduated.

In a groove bearing on the under side of the main bench, extending longitudinally to its end, is arranged a slide, G, which carries in its head H an adjustable rest, K, for the wheelspoke.

L represents a threaded post or center fasteniu g, on which the hub of the wheel is placed, being secured thereto bymeans of a lever-nut, N. This center fastening is adjustable, being sometimes secured in a bearing, 8, in the workslide 0, and sometimes in a bearing, 8, in the main bench nearer the spoke-rest. In the latter position it is used chiefly for securing the hub when the spokes are to be driven into the same, and the slide of the spoke-rest enables the latter to be moved outward from the end of the bench into proper position to support the spoke with relation to the center fastening.

In jointing an angularly-recessed back block, P, is employed, the same being secured to the work-table by'auy. ordinary clamping device. In the bearing-angle t of the back block the end of the spoke is laid and secured by means of a clamping-lever, R, which is pivoted to the back of the block, and is brought forward over the spoke, as indicated in the drawings.

The jointing-knives z a are parallel, and are held by the edges of their shank portions 2; in grooves r of the slides or plates to, these being seated in a hearing or head,f, which is attached to the end of the shaft 70. The plates to are connected to the head f by means of a rivet, and are held in engagement with the edges of the knives by means of a clamp-screw, a. The shanks of the knives are also connected by a clamp-screw, b, and by a second clamp-screw, 0, beyond the ends of the holding-plates,,which enables the cutting edges of the knives to be adjusted to the exact distance apart required for the thickness of the tenon to be formed. A set-screw, cl, serves to fix the position of the slide G of the spoke-rest after it has been adjusted.

V indicates a vertical screw, which is seated in bearings m and n, in connection with the main bench and the upright E or base of the adjustable post, and its threaded portion engages a threaded bearing, 0, of said post, as indicated in .the drawings. By turning the screw V the post D can readily be raised or lowered to bring the tool on an exact level with its work.

In operating this machine, which is chiefly designed to be employed in connection with the manufacture of wheels for'wagons and carriages, the work is moved horizontally up to the bit, auger, or jointing-knives by means of the treadles, the T-lever, and its rod connected to the work-table. The same devices also enable the operator to remove the work from the tool when finished. The tool-shaft k is pro- 1. In a boring and tenoning machine, the

treadles F and T-lever l, and the perforated adjustable rod m, connecting said T-lever to the work-table O, substantially as specified.
